In 20-sim, creating models only takes you just a few mouse clicks.
By dragging an element from one of the extensive libraries and
dropping it on your workspace, your model is actually built the
same way as you would draw an engineering scheme.
20-sim supports multiple model representations, causal as well
as acausal, all in the same model!
Iconic diagrams
Electric
- Various voltage and current sources
- Inductors, resistors, capacitors, etc.
- Diodes, op-amps and rectifiers
Hydraulic
- Orifices and laminar resistances
- Cylinders, accumulators, tanks
- Pumps and motors
- Valves
- Flow, power and pressure sensors
Thermal
- Heat capacity and heat flow
- Convection and radiation elements
- Sensors
- Heat generators
Mechanical
- Inertia's, springs, dampers, etc.
- Bearings, backlash and clutch models
- Advanced frictions models (LuGre, Dahl, KFM)
- Belts, spindles, gears and differentials
- Various types of sensors and encoders
All elements in the mechanical library are defined for the rotational
as well as the translational domain. Furthermore, there is a special
library for 2D and 3D bodies with small rotations

Signal blocks
- Gain, integrate, differentiate, delay, etc.
- Several filter models (Butterworth, Bessel)
- Discrete elements (AD, DA, sample, hold)
- Wave and signal generators
- Logical operators
- Various controllers
- more...
Bond graph elements
- Se, Sf, MSe, MSf, ...
- I, C, R, ...
- TF, GY, MTF, MGY, ...
- 1, 0, ...
- more...
Custom made library
20-sim enables you to adjust underlying equations of the library
elements to your specific situation, for instance non-linear friction
characteristics. You can even create your own dedicated libraries,
including matching icons.
All model equations are written in a Maple-like language which
is very easy to use and understand.
